While you are doing all the above to get rid of alge, the root of your problem is your SWG. It is not sensing any (or enough) water flow. The pump must be pumping water through your system for the SWG to generate chlorine. Make sure that the wires to the flow sensor and to the control box are not damaged and that the end is plugged into the box completly (maybe unplug it and plug it back in a couple of times to ensure a good connection and check for corrosion). If wires are ok, check the sensor itself to make sure that there is nothing blocking it (pull it out and check the ports) You might also try and clean it. 6.5 Flow/Temp/Salinity Sensor Cleaning
One time per year or as needed. It is rare but scale formations on the Flow/Temp/Salinity Sensor sometimes
occur and will affect the accuracy of the salinity test.
1. Remove Flow/Temp/Salinity Sensor from the threaded PVC Tee or 3-Port Cell by turning
counterclockwise or removing the union nut.
2. Brush with a mildly abrasive green fi ber household cleaning pad. Contacts should be clean and bright.
3. Thoroughly rinse the Flow/Temp/Salinity Sensor with clean tap water. Replace and resume normal
operation.
4. Turn power off and back on in order to recalibrate and reset Flow/Temp/Salinity Sensor. Reset
anytime Flow/Temp/Salinity Sensor is unplugged.
If that all fails I would replace the sensor.
You can get a replacement sensor for 150.00 to 200.00 on ebay.
Good luck!
